[@ZAVAZggg] Psionics are also a thing if a bit "limited". Think Telekinesis, limited mind-reading and such.

Edit: By the present time, the Xenos have been pretty much "uplifted" in a sense by humanity's arrival. Once communication was set up, the xenos that could, had reverse-engineered human tech to give themselves a technological boost. They're capable of using the above.
